You may not know PHP get_meta_tags () function _php Tutorial

definition and Usage:

get_meta_tags-extracts all meta tags from a file content property, returns an array

Parameters	Describe
FileName	Path string for HTML file This parameter can be a local file or it can be a URL. Example #1 Get_meta_tags () resolved what (Note that the carriage return line-PHP uses a local function to parse the input, so the files on the MAC will not work on Unix).
Use_include_path	Setting Use_include_path to TRUE will cause PHP to attempt to open the file with each point in the Include_path standard include path. This is used only for local files and not for URLs.

return value

Returns an array that contains all parsed meta tags.
The returned associative array takes the value of the property name as the key, the value of the properties content as the value, so you can easily traverse this associative array or access a value using a standard array function. The special characters in the property name are replaced with ' _ ', while the other characters are converted to lowercase. If there are two meta tags with the same name, only the last one that appears is returned.

Example

Copy the Code code as follows:
Assuming that the top label is in Www.jb51.net
$tags = get_meta_tags (' http://www.jb51.net ');

Note that all keys (key) are lowercase, and the key is '. ' is converted into ' _ '.
echo $tags [' author ']; DXY | Www.jb51.net
echo $tags [' keywords ']; Script, VBScript, regular expression, jquery,dos,bat, batch, javascript,photoshop,html,div+css,asp,php,asp.net
